Abstract

See full text

A viewing angle switchable liquid crystal display device includes a display panel. The display panel includes a first substrate, a second substrate disposed opposite the first substrate, and a liquid crystal layer disposed between the first substrate and the second substrate. The second substrate is provided with a first electrode and a second electrode. The first electrode is a common electrode, and the second electrode is a pixel electrode. The first substrate is provided with a third electrode for controlling the switching of the viewing angle. A periodic alternating voltage is applied to the third electrode when the viewing angle of the liquid crystal display device is switched, and a period of the periodic alternating voltage is an even multiple of a refresh period of each frame of the display panel.
